 *   ✅ Increment 3.2: Update Test Expectations for New Default and Re-baseline Failures
-    *   (Details as before)
+    *   Target Component(s): All test files in `module/core/strs_tools/tests/inc/split_test/`.
+        *   `basic_split_tests.rs`
+        *   `preserving_options_tests.rs`
+        *   `stripping_options_tests.rs`
+        *   `quoting_options_tests.rs`
+        *   `combined_options_tests.rs`
+        *   `edge_case_tests.rs`
+        *   `indexing_options_tests.rs`
+    *   Pre-Analysis: `preserving_delimeters` now defaults to `true` in `SplitOptionsFormer::new()`. Many existing test assertions (both those that were passing with the old default and those that were failing) might now be incorrect if they relied on the implicit `preserving_delimeters: false`.
+    *   Detailed Plan Steps:
+        1.  **Systematically Review and Update `basic_split_tests.rs`:** (Completed)
+        2.  **Systematically Review and Update `preserving_options_tests.rs`:** (Completed)

+        9.  **Identify and Comment Out Failures:** (Completed - No new failures)
+        10. **Update Plan File with Failing Tests:** (Completed - No new failing tests to list)
+    *   Crucial Design Rules: Critical Log Analysis, Minimal necessary change (to test expectations).
+    *   Relevant Behavior Rules: Adherence to the new default for `preserving_delimeters`.
+    *   Verification Strategy:
+        1.  User reviews a sample of updated test expectations during the modification phase. (Completed implicitly)
+        2.  User provides the full test output from Detailed Plan Step 8. (Completed - All tests passed)
+        3.  After commenting out newly failing tests (Detailed Plan Step 9), request the user to run the tests again. (Completed - No tests needed commenting)
+        4.  User reviews the updated list of failing tests in the plan file. (Completed - List is empty)

     *   Target Component(s): `strs_tools` crate, especially `tests/inc/split_test/` and `src/string/split.rs`.
     *   Pre-Analysis: All tests in `inc::split_test` are currently passing with the new default for `preserving_delimeters`. The Test Matrix drafted in Increment 1 needs to be reviewed against the current test suite.
     *   Detailed Plan Steps:
-        1.  **Review Test Matrix vs. Current Tests:**
+        1.  **Review Test Matrix vs. Current Tests:** (In Progress - Test Matrix ID comments added to all files in `inc::split_test`)
             *   Load the Test Matrix from Increment 1 (or its latest version if it was updated).
             *   For each combination in the Test Matrix:
                 *   Verify if a corresponding test exists in `tests/inc/split_test/`.
                 *   Ensure the test name clearly reflects the matrix combination it covers.
                 *   Ensure the test logic correctly implements the options and checks the expected outcome as per the matrix and the new `preserving_delimeters: true` default.
-                *   Add `// Test Matrix ID: [Matrix_Row_ID]` comment to each test function.
+                *   Ensure `// Test Matrix ID: [Matrix_Row_ID]` comment is present and correct.
         2.  **Identify Coverage Gaps:**
             *   List any Test Matrix combinations that do not have a corresponding test or where the existing test is insufficient.
         3.  **Implement Missing Tests (if any):**
